SPECIFICATION forming part of Letters Patent No. 745,138, dated November 24, 1903. Application filed J'uly'l, 1903, Serial No. 163,849. (No model.)

To all whom t may concern: 1

Be it known that I, CHARLES W. BEEI-ILER, a citizen of the United States, residing in the city of St. Louis, in the State of Missouri, have invented certain new and useful Improveruentsl in Box-Fasteners, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings, forming part of this specification.

My invention relates Vto an improvement on a box-fastener described in Letters Patent of the United States granted t'o me March 11, 1890, No. 423,303.

The present improvement has for its object to provide a construction wherein the catch-spring of the fastener may be more readily disengaged from the catch of the fastener lid-plate.

It has for its further object the provision of means by which the catch-spring is protected to prevent its being accidentally disengaged from the lid-plate catch.

The invention consists in features of novelty hereinafter fully described, and pointed out in the claims. A

Figure I is a top view showing a portion of a box with myimproved box-fastener applied thereto. Fig. II is a vertical sectionv taken on line II II, Fig. I. Fig. III is a vertical section taken on line III III, Fig: II.

A designates a part of the front wall of a box to which my fastener, as shown, is applied, and B a part of the box-lid. In the lid B at the location to which the fastener is to be applied is an aperture C.

l designates a catch-spring of loop form that is secured to the front wall of the box by staples 2. The upper loop end'of this spring-arm is adapted to pass through the lid-aperture C to project above the top of the lid when the lid is in lowered position.

4 designates a sheet-metal lid-plate that is secured to the lid B by any suitable means, such as nails. In the lid-plate is an opening 5, that registers with theaperture C in the lid. The central forward portion of the lidplate is bent upwardly into inverted- U shape to form a rearwardly-extending catch 6, that projects partially over the lid-aperture C to receive the loop end of the spring-arm 1, which passes thereover to engagesaid catch.

ing of the box.

Fig. III.

The raised portion of the lid-plate from which the catch 6 is formed has a straight upper face 7 extending from the outer end thereof to the inner end of the catch, as seen in Figs. I and Il. In forming the catch 6 of the lidplate the metal is cut away at the sides of the catch and bent downwardly to produce vertical tongues 8, that have rear beveled faces 9, (see Figs. II and III,) against which -the spring-arm l rides to directits travel upwardly to the catch 6 when the lid of the box is lowered. It will therefore be seen that the loop of the spring-arm will pass readily upwardly and onto the catch without assistance. By making the central portion of the lidplate which carries the catch 6 of straight form forward of the catch -it will be seen that the catch-spring may be readily engaged by the operators fingers to be pushed olf of the catch, when the spring-arm would be disengaged from the lid-plate to permit the open- I thus overcome an objection to the fastener illustrated in my patent hereinbefore referred to, in which a flange exists forward of the lid-plate catch, thereby necessitating the employment of a tool to be inserted at the rear of said flange to move the spring-arm od of the catch owing to its being difiicult to grasp the spring-arm with the fingers. At each side of the opening 5 in the lid-plate I form vertical ribs 10, that project upwardly beyond the level of the spring-arm when it is in engagement with the lid-plate catch, thereby affording protection for the spring-arm to prevent its being struck and accidentally thrown 0E of the catch.v Such disengagement is liable to occur frequently where boxes are stacked one upon another in the absence of protection for the spring-arm., The ribs 10 are produced bybending the sheet-metal lid-plate upwardly at each side of the catch 6, as most clearly seen in The raised central portion of the lid-plate affords an aperture through which a seal-wire may be passed to encircle the springarm when it is in engagement with the lidplate, as shown by dotted lines, Fig. II.

I claim as my inventionl. In a box-fastener, the combination of a spring-arm and a lid-plate having a struckup central portion with an upper straight face integral with said plate, and a catch de- ICO pending from said struck-up portion to reoeive the engagement of said spring-arm substantially as set forth.

2. A lid-plate for a box-fastener having a struck-np central portion having a flat upper face, tongues having beveled faces depending from the inner end of said struck-up eentral portion, and vertical ribs projecting np- Wardly from the plate toa point above the struck-up Central portion and extending the full width of the plate.

3. In a boxefastener, the combination of a ldplateooxnprising a plate having a struckup central portion having a fiat upper' face, tongues having beveled faces depending from the inner end of said struck-np central portion, and vertical ribs projecting upwardly from the plate to a point above the struck-up central portion and extending the full Width of the plate, of a looped spring lookingfarm zo to engage saidstruok-np central portion.
